2026 BMW X1 Check Engine Light Codes

The most common check engine light codes for a 2026 BMW X1 encountered at Nalley BMW of Decatur include P0420 (catalyst system efficiency), P0171/P0174 (fuel trim/system lean), and various oxygen sensor or evaporative emission (EVAP) codes.

Lean fuel codes can cause rough running, reduced fuel economy, and long-term engine wear—repairing the root cause saves on fuel and engine service over time. EVAP or fuel cap issues are typically inexpensive to fix when identified early. Our certified BMW technicians in Decatur use OEM parts and manufacturer-grade diagnostics to pinpoint the exact cause, often resolving issues faster than independent shops and at lower total cost due to fewer follow-up repairs.
